Hollow fibers with the internal silver and polymer layers have been developed for delivery of high energy pulses of infrared lasers. We adopted a cyclic olefin polymer (COP) as the dielectric layer. Since this polymer exhibits no strong absorption in the Er:YAG (2.94 μm) or Nd:YAG (1.06 μm) wavelength region, it is appropriate for inner dielectric of hollow fibers. We fabricated the COP-coated hollow fibers by using a liquid-flow, polymer coating technique. We report our recent results on transmission properties of the polymer-coated fibers for Er:YAG and Nd:YAG lasers.
